I bought the Catfish. It ran fine the first time out of the box, but the second time (the next weekend) after a full overnight charge, it ran literally long enough for me to get it to the floor of the pool and just shut off. Not a gradual dying down, just boom, lights out. Pulled it out, sat it on the deck, drug out the hoses, and went at it the old fashioned way. Tried it again about 30 minutes later and it fired right up. Went ahead and used it, and it ran fine for the remainder of the pool.

The next weekend, again after an overnight charge, this time it wouldn't even turn on period after coming off the charger. However, same thing again; about 30-40 minutes later, it fired right up and then ran fine.

Called the support number, waited thru the long string of prompts, don't remember exactly why but ultimately finally decided I would just e-mail tech support. Adam responded promptly, we exchanged a few e-mails, and he finally instructed me to ship it back and he would send a replacement. By that time however, the unit had since worked properly twice in a row (by "worked properly" I mean it started up immediately and stayed running when taken off of the charger). Because of this, and the fact that returning the unit would have been at my expense which struck me the wrong way given what I had already paid about a month prior, i notified Adam that thanks, but I'd just keep it.

The unit has run fine ever since. Not as powerful as a regular hose-suction vacuum for sure (nor do I think it was intended to be) and it seems a bit overpriced, but for vacuuming bugs and small residue it works pretty good. I don't have the fine silt bag; I use the cotton ball approach advocated elsewhere on this forum, and have had no problems.

Would I buy another one? Errr...ummm....let me get back to you on that.
